I recently noticed one of my bp has a white spot under her lower inside lip. I did an online search which matches something of a mouth fungus. My water conditions are fine: 0 ammonia, 0 nitrite, 15 nitrate, 84 degrees My 2 bps share a 50 gallon tank with 10 tiger barbs and 2 nerite snails. This is the first time any bacterial infections have happened. I just did a 50% water change today and added aquarium salt. My bp seems to be normal and still eats. Hopefully in a few days the mouth fungus will go away. Has anyone had any mouth fungus with your bp?
